All good Ray, Can't change it, just got to fix it now, finally split the cases last night, OH DEAR, more bad news. The both of the case halfs have a visable crack of approx 20mm at the bottom of what I would call the crank shaft chamber. Probably will be able to repair but that depends on how well it tigs up. The cracks for want of a better word, are on an internal wall so not as bad and the fact that the case halfs run a gasket is a bonus.....(would upload some photos if I new how) So far the parts list is, top end piston and gasket set, oil pump rotors, complete crank asembly, all lower case bearings etc as contaminated with metal particles, cases if the weld repair is not successfull.....I havn't finished pulling the top end apart yet but would appear as the valves and cams etc are ok at this stage.....It is going to be costly I would envisage, will find out over the next couple of days but am estimating approx $2000 with out cases. Can't actually figuer out how the cases cracked as the main bearings don't appear to be damaged only the bigend and I don't see how that could possibly hit the cases. More investigations tonight after work, last day on shift then 5 off so should have some answers hopefully soon
